Before I make my point, correct me if I am wrong.
In sHMD, when 2 level of refinement for the surface are defined, one of the factors resulting in the higher level of refinement is the resolveFeatureAngle. Of which any angle higher than the specified angle will have the maximum level of refinement specified.

Doesn't it sound weird to have higher refinement when the angle is larger as this would mean a gentler curve, edge, corner etc. Normally, parts that are harder to get are areas with sharp edges (lower angle).

For example a wedge (90 degree) on a plate (180 degree). With a resolveFeatureAngle of 100 degree would make the plate have the maximum refinement level (as 180 > 100) and the edge between the plate and the wedge at a lower refinement level (as 90 < 100).

Is there other way to manipulate or use this function?

Due to the absence of replies, and in order to highlight that there are others who have encountered this strange interpretation and perplexing conclusion, I would like to say that I have the same interpretation as you do, and do not understand what the parameter is supposed to do given the way I interpret its function. I can see no other than your interpretation to:

"resolveFeatureAngle Applies maximum level of refinement to cells that can see intersections whose angle exceeds this."

and yet I cannot square it with the intention of, as you say, having higher refinement applied to large rather than small angles.

It would be greatly appreciated if someone more knowledgeable could give some clarity into the matter.

I know it is a late, but I've found an interesting explication of the resolvefeatureangle in this presentation, starting from the 220 page of the following pdf: http://www.dicat.unige.it/guerrero/o...ng/module3.pdf

I hope it helps!
